Algorithms for determining the phase of RHEED oscillations

What is it about?

Oscillations of reflection high-energy electron diffraction (RHEED) intensities are computed using advanced, diffraction theory (in which multiple scattering events are taken into account). The phase of the oscillations is determined using two different approaches: direct one and the other, employing harmonic analysis. The advantages and disadvantages of these two approaches are briefly discussed. Then, the phase of RHEED oscillations observed experimentally is analysed. For incident-beam azimuths corresponding to low-symmetry directions, both approaches produce similar results.
